BSc Zoology with Industrial/Professional Experience

Excitable cells - cells which respond to stimuli by producing an electric current - are key to the function of our muscles and nervous system. You will learn about the structure and function of these cells, what makes them important and the techniques used to study them.

To consider the major concepts underlying the basis of cell excitability, the structure and function of excitable cells and their contribution to muscle and nervous system function.

At the end of this unit, students will have developed an understanding of what excitable cells are and what makes them important. Key features of how excitable cells maintain and alter their ionic composition in relation to electrochemical gradients will become familiar. Students will understand the techniques used to study excitable cells; in addition, students will become familiar with a variety of cells within the nervous system and how they function, such as sensory and motor neurons and how these relate to muscles. Students will then be able to begin to apply this knowledge in learning about how networks of excitable cells can function together as higher level systems, such as those involved in learning and memory.

Students will be expected to complete 1 eLearning module per week, containing approximately 1 hour of pre-recorded video content or equivalent

Each week there will also be 1 hour of live-lecture content that builds on the eLearning module and a 1 hour face-to-face active learning session. 

Each week students will complete 1 hour of eLearning content.

90% awarded for the unit examination which will consist of 50 multiple choice questions, in the semester 2 examination period. 10% awarded for online summative multiple choice question-based assessments.

Feedback on coursework MCQs will be provided via the Blackboard MCQ system. Formative feedback will be available via revision reversions of summative assessments and an online version of a past year’s exam paper. Cohort level feedback will be provided after the exam, with individual exam guidance available upon request.
